Bukhari :: Book 5 :: Volume 59 :: Hadith 618
Narrated Safwan bin Ya'la bin Umaiya:
Ya'la used to say, "I wish I could see Allah's Apostle at the time when he is being inspired divinely." Ya'la added "While the Prophet was at Al-Ja'rana, shaded with a cloth sheet (in the form of a tent) and there were staying with him, some of his companions under it, suddenly there came to him a bedouin wearing a cloak and perfumed extravagantly. He said, "O Allah's Apostle ! What is your opinion regarding a man who assumes the state of Ihram for 'Umra wearing a cloak after applying perfume to his body?" 'Umar signalled with his hand to Ya'la to come (near). Ya'la came and put his head (underneath that cloth sheet) and saw the Prophet red-faced and when that state (of the Prophet ) was over, he said, "Where is he who as already asked me about the 'Umra?" The man was looked for and brought to the Prophet The Prophet said (to him), "As for the perfume you have applied to your body, wash it off your body) thrice, and take off your cloak, and then do in your 'Umra the rites you do in your Hajj."
